Authors:RV Brunsdon MSc PhD

Abstract:Extract

Although Nematodirus species are commonlyfound in sheep in New Zealand, the worm had been considered to be of little economic importance until the period 1956–9 when a number of outbreaks of acute disease occurred in lambs; the condition was ascribed to heavy Nematodirus infestation. A similar situation had existed in the British Isles until about 1951 when outbreaks of acute nematodiriasis reached serious proportions.
